Allen-Bradley 1769-CRR1 Compactlogix Bus Expansion Cable

Description

The Allen-Bradley 1769-CRR1 CompactLogix Bus Expansion Cable is a dedicated bus extension component for the Allen-Bradley CompactLogix series, designed for short-range interconnection between controllers and compact I/O modules in industrial automation scenarios. Key technical specifications include a 1-foot (305 mm) cable length, a net weight of 0.28 kg, and a shipping weight of 1.5 kg, making it compact and lightweight for easy installation in space-constrained electrical cabinets. Its electrical performance features a 30V continuous isolation voltage, a backplane current of 1.4A at 24V, a power consumption of 33.6 watts, and a power loss of 7.5 watts, ensuring stable bus power supply and signal transmission for Compact I/O modules. The cable operates reliably in a temperature range of 0 degrees Celsius to 60 degrees Celsius (32 to 140 degrees Fahrenheit), suitable for conventional industrial site conditions. As a passive connection component, it supports close-range bus expansion for CompactLogix local racks, helping to meet the need for flexible I/O system configuration in applications such as packaging machinery, material handling, and small to medium manufacturing units.
